You can use the SchemaExport class from NHibernate Core to export your schema to a database.

To execute the schema export, use the ExposeConfiguration method in the Fluent NHibernate database configuration API.

var sessionFactory = Fluently.Configure()
   .Database(/* ... */)
   .Mappings(/* ... */)
   .ExposeConfiguration(cfg => new SchemaExport(cfg).Execute(true, true, false))
   .BuildSessionFactory();

There's also a SchemaUpdate class available which does not drop and recreate your schema but updates the existing schema. This is useful if you would like to preserve the data in the database.

SchemaExport and SchemaUpdate are available in the NHibernate.Tool.hbm2ddl namespace.
